The recall affects certain 2010-2011 model year Dodge Ram trucks built from March 2009 through October 2010.
Chrysler said some trucks with diesel engines and a hydroboost brake system could be equipped with a power steering reservoir cap with excessive vent pressure levels.
The excessive levels could lead to brake pedals that are slow to return and cause the brake lights remain on, potentially causing a crash.
Chrysler spokesman Vince Muniga said there have been no crashes or injuries reported. He said the problem was first noticed by dealers and a modified cap will relieve some of the pressure causing the problem.
Chrysler said it will notify owners. Dealers will replace the steering reservoir cap free of charge.
